"It is starting to ramp up, our peak is about to come in July and August," Dr Dilip Dhupelia from the Australian Medical Association told 9NEWS.

Last year 753 patients had symptoms so severe they were placed in intensive care.

"Doesn't matter how fit and healthy you are it's unpredictable when you do get the flu," Dr Dilip Dhupelia said.

"Right now if you are sick you need to do the right thing by your community, by your fellow employers by your fellow workers and your fellow students, stay at home."
